For superior safety and freedom of movement, the 2011 Alpinestars SMX Plus Boot features an innovative Multi Link Control system and high modulus TPU protection integrated into the sleek profile of the boot. The inner Kevlar® speed lacing closure and micro-adjustable ratchet fastener combine to ensure a comfortable, conforming fit on both the road and track.
Forefoot laminated with shock absorbing open cell foam while the ankle area has a highly breathable lining for improved comfort.
Alpinestars unique Multi Link Control System provides advanced support for the ankle, limiting hypertorsion, hyper-extension and hyper- flexion as well as providing additional impact protection to the ankle and Achilles.
Wide, ventilated, heel counter extends to the ankle and is combined with a shock absorbing padded insert and self-molding foam ankle protectors.
Replaceable heel slider and external side heel slider are positioned to dissipate shock and promote sliding during an accident.
Newly designed, replaceable TPU toe slider with snap-in assembly provides more coverage around the toe area
Perforated leather construction makes this boot ideal for warm weather conditions

Kemar S: I choose to buy these boots because I wanted something with a lot of protection just incase I went down while riding. I since I have own these boots I loved every thing about them. it's going on two years since I have own them and they still have a lot of wear left in them. They are really comfortable and breathable depending on the kind of soaks I'm wearing. I actually recommended these boots to my fellow rider and he bought the ones one step below this these.Aug 21, 2013
A shopper asked:I think the question is probably pretty clear. It is hard to get a feel for how big the boots are on your leg. If I were to wear pants, would they easily fall over the top part of the boot? Jeans? Dress pants (although I don't know why I would wear those while riding)? What about riding pants?
antbrdwar:Riding pants shouldn't be an issue. The boots don't come up too high (compared to other Dainese boots) but could pose a problem if you have large calves. Personally, I wear "comfortable" "loose" jeans when I ride and they fit over these boots without a problem. Dress pants that are normal and "flowy" for lack of better terms shouldn't pose a problem, though the hipster "fitted" pants most definitely would.Apr 1, 2013
RevZilla:Most textile riding pants will fit over these boots, no problem. The issue with jeans is that there are skinny jeans, wideleg jeans, and varying widths in between. If the circumference of your pants is at least 2-3 inches more than the circumference of your calf, though, there should be enough space to accommodate the boots.Mar 22, 2013
CWinfrey:Unless you have a really wide leg pair of pants or jeans I do not think that they would fall over the top of the boot. This book is more of a race/track book and less of a street bookMar 26, 2013
A shopper asked:Looking to purchase these boots but not quite sure on which size to get. I've never had A* boots. I'm in between 10.5-11US. Not sure if I should get a 44 or 45 Euro. If the sizing runs a bit large as some of the reviewers suggested, I suppose a 44 should be good but I'm just not sure! Help!May 24, 2013
Hombie:I too am between a 10.5 U.S. and 11 U.S. depending on brand. I ordered a size 45 and have a little wiggle room in them. Not much, but i wear a thin sock when I ride. I would recommend the 45 and let your feet breath.Jun 2, 2013
A shopper asked:I'm mainly concerned about toe/heel and ankle protection. I'm coming from a pair of puma 1000's which were very protective. I want something similar to that level of protection, but the boot needs to be comfortable enough to walk around in almost daily and be easy to get on and off. I do 90 percent street riding (some what agressive) and a few track days a year. thanks for you're imputFeb 5, 2012
RevZilla:In terms of ankle protection, our choice would be the Dainese TRQ. The Dainese boot allows very minimal side to side movement of the ankle where as the SMX Plus is only reinforced on the outer facing side, making it vulnerable to bending on the inside. Both the SMX Plus and the Dainese TRQ are very comfortable (dependent on your foot of course) to wear around. If we chose one that was easier to live with for commuting and getting on and off, it would be the Dainese TRQ. It's just less complicated on the inside.Apr 13, 2012
Chrissy:I broke my ankle several years ago and still have a plate in it so protection and comfort where keys points for me. These are hands down the best in my opinion, I can walk any distance with no discomfort at all. That inner boot makes all the difference.Apr 8, 2013
